In particular to a bridge chord, two wing plates are higher and are generally higher than the upper surface of the end head by about 1 meter to 2 meters, which is inconvenient to process. In the three-face drilling equipment in the prior art, due to the fact that the cross beam is heavy and is of a fixed structure generally, in order to avoid the height of the wing plate, the position of the cross beam is higher, the extension length of the power head is limited, the vertical power head is not easy to install on the cross beam, and therefore holes on the upper surface of a workpiece cannot be machined.

The original processing of the bolt holes of the steel structural members is mainly manual scribing and manual processing. Some devices can process wing plates on two sides, but cannot process holes on the upper surface of the chord member, the workpiece needs to be turned over for 90 degrees for secondary processing, or manual supplementary processing is performed, and the large workpiece is turned over and aligned, so that the time consumption is high and the efficiency is low.

In addition, in the prior art, although there is also processing equipment with one vertical power head and two horizontal power heads, under normal conditions, three power heads are positioned in the same processing section, and the horizontal power heads cannot be independently adjusted in the horizontal direction, so that the three power heads can only feed simultaneously when drilling, can only realize the simultaneous processing of three directional holes in the same section, and cannot realize the processing of three directional holes in different sections. In the actual machining process, because the two side wing plate holes of the steel structural member and the upper drilled holes are not in the same section, often the difference is tens of millimeters, and therefore, the machining of the holes in three directions cannot be simultaneously realized by the three power heads in the prior art.
